 Gas Exchange – it allows oxygen from the air to enter the blood and carbon dioxide to leave the blood.  Regulation of Blood pH – by changing blood carbon dioxide.  Voice Production vocal cords.

– air movement passes the

 Olfaction – when airborne molecules are drawn into the nasal cavity.  Innate Immunity – provides protection against microorganisms by preventing their entry into the respiratory surfaces



It is the inflammation of the bronchi caused by irritants, like smoking or infections.



It results to swelling of the mucous membrane lining the bronchi, increased mucus production, and decreased movement of mucus by cilia.

It

is the destruction of the alveolar walls.

 Narrowing

of the bronchioles restricts air movement, and air tends to be retained in the lungs.

 It

is an inherited disease that affects the secretory cells lining the lungs, pancreas, sweat glands, and salivary glands.

 It

is the replacement of lung tissue with fibrous connective tissue, making the lungs less elastic and breathing more difficult. Exposure to asbestos, silica, or coal dust is the most common cause.

 It

arises from the epithelium of the respiratory tract.  It is the most common cause of cancer death in males and in females, esp. smokers………
